An onshore AR firm. A company in your own country, often run by accountants or former credit controllers, that takes on the work for several clients. You get people who know local practice and work your hours. They are usually the most expensive route per hour, and some set a minimum monthly fee.
An offshore team. A company abroad, commonly in the Philippines or India, that provides staff to work your receivables, either dedicated to you or shared across clients. The hourly cost is the main attraction. In practice you often supply the process, the templates and the training, and someone on your side reviews the work, so it suits businesses that already have a clear process to hand over.
A freelancer or virtual assistant. One person, found directly or through a marketplace, working a few hours a week. Flexible and inexpensive for small volumes. You depend on one person, and there is nobody else when they are away.
An AI agent with a team overseeing it. Software connects to your accounting system and inbox, follows up overdue invoices, reads replies and tracks promises, and people review the cases that need judgement. You pay for the work done rather than for hours, and the history of every email and promise is kept in one place. It covers follow-up and reply handling, not every AR task. Our guide to an AI collections agent explains what it should and should not do alone.
